Run the pump at ultimate vacuum for one hour and set the nitrogen flow rate
as follows (at atmospheric pressure and at 20°C).
Note: these characteristics apply for pumps operating at a constant inlet
pressure (1 to 5 mbar): they are adapted for each case of pumping.
Start-up the pump at ultimate vacuum. When it is hot, run the nitrogen purge.
Use it from the beginning and throughout pumping.
When pumping stops, allow the purge to operate for approximately 1 hour
(depending on the quantity of pumped gas) at ultimate vacuum, with the
purge, in order to degas the oil effectively and clean the pump with nitrogen
to eliminate the traces of pumped gases.
